The stability of dihalides of Si, Ge, Sn and Pb increases steadily in the sequence

  • GeX2 << SiX2 << SnX2<< PbX2

  • SiX2 << GeX2 << PbX2<< SnX2

  • SiX2 << GeX2 << SnX2<< PbX2

  • PbX2<< SnX2 << GeX2 << SiX2

Solution

C.

SiX2 << GeX2 << SnX2<< PbX2

Due to inert pair effect, the stability of +2 oxidation state increases as we move down this group.
